As you can see from the picture, there are small feets on 
the bottom which can be folded out. Please make sure you 
have fully folded out the feet‘s in order to ensure stability 
of the instrument.

The instrument must be installed in a way, that at any time 
the disconnection of the power line is not restricted.

The instrument fulfils the DIN EN 61010-1 (VDE 0411 part
1) regulations for electrical measuring, control and labora-
tory instruments and was manufactured and tested accor-
dingly. It left the factory in perfect safe condition. Hence it 
also corresponds to European Standard EN 61010-1 and In-

ternational Standard IEC 61010-1. In order to maintain this 
condition and to ensure safe operation the user is required 
to observe the warnings and other directions for use in 
this manual. Housing, chassis as well as all measuring ter-
minals are connected to safety ground of the mains. The 
instrument is designed in compliance with the regulations 
of class I.

The exposed metal parts are checked against the mains 
poles with 2200 V

 voltage. The instrument is in ac-

cordance with overvoltage category II. For safety reasons, 
the instrument may only be operated with authorized 
safety sockets. The power cord must be plugged in before 
signal circuits may be connected. Separating the grounds
is prohibited.

Never use the product if the power cable is damaged. 
Check regularly if the power cables are in perfect condi-
tion. Choose suitable protective measures and installation 
types to ensure that the power cord cannot be damaged 
and that no harm is caused by tripping hazards or from 
electric shock, for instance. If it is assumed that a safe 
operation is no longer possible, the instrument must be 
shut down and secured against any unintended operation. 

 ❙in case of visible damage,
 ❙in case loose parts were noticed,
 ❙if it does not function any more,
 ❙after prolonged storage under unfavourable conditions 

(e.g. like in the open or in moist atmosphere),

 ❙after rough handling during transport (e.g. packaging that 

does not meet the minimum requirements by post office,
railway or forwarding agency).

The measuring instrument is intended only for use by per-
sonnel familiar with the potential risks of measuring electri-

cal quantities. For safety reasons, the instrument may only 
be connected to properly installed safety socket outlets. 
Separating the grounds is prohibited. The power plug must 
be inserted before signal circuits may be connected. The 
product may be operated only under the operating condi-
tions and in the positions specified by the manufacturer,
without the products ventilation being obstructed. If the 
manufacturers specifications are not observed, this can
result in electric shock, fire and/or serious personal injury,
and in some cases, death. Applicable local or national 
safety regulations and rules for the prevention of accidents 
must be observed in all work performed.
